DNA extraction methods such as plasmid minipreps, gel, and PCR purifications, are indispensable techniques for genetic manipulations. There are numerous factors that contribute to the efficiency of these processes, which determine the success of complex downstream molecular analytics and diagnostic tests. To study and optimize these factors, we compared our own proprietary buffers to commercially available column-based kits, utilizing their spin columns and protocols. Through systematic substitution of the buffers in the kits with our own proprietary buffers, we selected the highest DNA yielding buffer recipes. Further analysis of the differences between the buffers showed that high concentrations and presence of certain chaotropic agents and cations are necessary for good plasmid miniprep, gel extraction, and PCR purification kits.
